Definitions

  • This invention relates to a disposable pressure container, in particular for use as a refill container for refrigerating and air conditioning systems, comprising a combined filling and removing valve which has a filling and removing opening and includes a valve body which is displaceably guided in a bore of a valve housing and urged by a resilient force against a valve seat and which is liftable from the valve seat against the action of the resilient force for filling the pressure container and for removing the pressurized contents of the container, and which includes a second valve body which, before the container is filled for the first time, is held in space-apart relationship with its valve seat by a surmountable and fluid-permeable barrier, a tappet which is actuable from the filling and removing opening and acts on the second valve body being provided for urging the second valve body beyond the flexible barrier, whereby the second valve body forms a check valve with its valve seat after the barrier has been surmounted, the check valve preventing the container from being filled again.
  • a disposable pressure container of the above-mentioned kind is known from U.S. Pat. No. 3,704,813.
  • This pressure container has already the advantage that it prevents refilling.
  • the valve housing is relatively troublesome from a constructional point of view, and its manufacture is thus expensive.
  • valve housing is made integral with a first bore for receiving the first valve body and a second bore for receiving the second valve body of plastics, that at the end opposite to the first valve seat the first bore comprises a radially inwardly oriented shoulder which is integral with the housing and on which a helical spring urging the first valve body against the first valve seat is supported on the one hand and the barrier for the second valve body is formed on the other hand, the shoulder comprising projections that project radially inwards into the circular plan view of the second bore and are also made integral with the valve housing of plastics
  • valve housing can thus be manufactured in a simple way as an injection-moulded part, made e.g. of polyamide, or the like. Hence, a substantial safety advantage can be achieved at very small costs
  • the projections can be constructed in a very simple way if designed as radially inwardly positioned ends of radial webs that are arranged on the shoulder and evenly distributed over the circumference. These webs lift the second valve body from the shoulder when the container is filled for the first time, so that during the filling operation fluid can flow through passages defined by the webs into the smaller second bore and thus into the container.
  • the projections taper to the first larger bore when viewed from the second smaller bore.
  • the valve body which is within the second smaller bore after the first filling operation is centered by the projections when fluid is removed from the container, whereby a uniform annular gap is formed through which fluid can flow into the larger bore.
  • the second valve body is made rotationally symmetrical and has a smaller diameter than the second bore.
  • the helical spring is preferably supported on the webs formed on the shoulder and has an inner diameter slightly greater than that of the second valve body.
  • the helical spring thus forms a guide for the second valve body when after the first filling the second valve body is pushed with the aid of the tappet through the barrier into the second smaller bore.
  • the second valve body is a ball which is preferably made of a harder material than the projections.
  • a preferred material for the ball is glass or steel while polyamide is preferably used for the valve housing and the projections.
  • the tappet is surrounded by and in spaced-apart relationship with a collar of the first valve body, and the helical spring acts on the first valve body within the space formed between tappet and collar.
  • FIG. 1 is a diagrammatic sectional view of a disposable pressure container comprising a filling and removing valve in accordance with the invention.
  • FIG. 2 is an enlarged view of the filling and removing valve shown in FIG. 1.
  • FIG. 1 shows a pressure container 1 which is closed by a cover 2.
  • Cover 2 is connected to the upper edge of container 1 by means of a flanged closure.
  • a substantially cylindrical elevation 3 whose center is equipped with a filling and removing opening 5 is provided in the middle of cover 2.
  • the outside of elevation 3 is equipped with a thread 6 for screwing a filling and removing head thereonto. This head is not shown for the sake of clarity.
  • Elevation 3 encloses a filling and removing valve 4 which is gripped from behind by a surrounding embossed portion 7 and retained within elevation 3.
  • Valve 4 comprises a valve housing 8 which is sealed by a sealing disc 9 with respect to the upper end of elevation 3.
  • a first large bore 10 is provided within sealing housing 8 and has displaceably arranged therein a first valve body 11 coaxial to bore 10. At its side facing the filling and removing opening 5, the first valve body 11 has a sealing collar 12 which cooperates with the sealing disc 9 surrounding opening 5.
  • valve body 11 is pressed together with its sealing collar 12 by a helical spring 13 against sealing disc 9.
  • Helical spring 13 is indirectly supported on a shoulder 14 disposed opposite to filling and removing opening 5.
  • Shoulder 14 is followed in axial direction by a second bore 15 of a smaller diameter which terminates in the interior of the container and whose end facing away from shoulder 14 has a conical valve seat 16 formed thereon.
  • Five radially inwardly oriented webs 17 whose free ends 18 project into the cross section of the second bore 15 are arranged on shoulder 14. When viewed from the smaller bore 15, the free ends 18 taper to the larger bore
  • Guide ribs 19 which extend in parallel with the bore axis are provided for the first valve body 11 on the edge of the larger bore 10. In the area of the shoulder these guide ribs 19 taper to the center of the bore, thereby forming a guide for the end of helical spring 13 which rests on webs 17.
  • the first valve body 11 has a tappet 20 which faces the second smaller bore 15 and is integral with the first valve body.
  • Tappet 20 is surrounded by and in spaced-apart relationship with a collar 21 that faces shoulder 14 and pertains to the first valve body 11.
  • Helical spring 13 is seated in the annular gap formed by tappet 20 in collar 21 and is supported on the gap bottom relative to the first valve body 11.
  • tappet 20 ends at some distance in front of webs 17. The distance is chosen such that a ball 22 whose diameter is slightly smaller than the diameter of the second bore 15, but greater than the clearance of the free ends 18 of webs 7 fits into the interspace.
  • FIGS. 1 and 2 illustrate a state of the pressure container before the same is filled for the first time.
  • the first valve body 11 is urged by spring 13 against seal 9, and the second valve body, i.e. ball 22, is still positioned in the large bore 10 in front of webs 17.
  • the second valve body i.e. ball 22
  • the first valve body 11 is again lifted from its seat through a mandrel.
  • the pressurized container ball now tries to move through the smaller second bore 15 into the larger bore 10.
  • Ball 22 which is now positioned in the smaller bore 15 is pressed from the rear side against the free ends 18 of webs 17.
  • Ball 22 is centered due to the oblique construction of the free ends 18 of the webs, so that the exiting fluid evenly flows around the ball and into the larger bore to pass through the annular gap formed between the first valve body 11 and the wall of the large bore 10, and between sealing disc 9 and the lifted valve body 11 to the outside.
